Question

Quizplus · Accepted Answer

Firewalls primarily perform access control functions such as filtering incoming and outgoing traffic based on predefined rules. They may also perform NAT (Network Address Translation) and packet inspection, but not necessarily encryption. Encryption is typically handled by dedicated encryption devices or protocols such as TLS (Transport Layer Security) implemented at the application layer.
